Leonardo, Great looking job. You could eliminate the anti-syphon if you didn't have the fresh water flush direct into the dump. Couldn't you eliminate that and just flush with the same hose that you use to clean out the RV's tank. You wouldn't have to worry about fresh water contamination. It's obvious you did some planning and thought to your project. Great job...

Never connect the frsh water to a sewer connection. You MUST have a vacuum breaker installed in that water line and or a double check valve. The potential to back sewage up into the water line exist the way you have it piped. It will never pass a plumbing inspection.

Once again I'd like to thank you very much for your compliments but especially your opinions regarding the fresh water to the black and grey water connection.

Even though it sounded like a good idea at the time, after taking into serious consideration your opinions, I have decided that there wouldn't be any save device that would stop the germs from spreading into my fresh water. But the safest thing to do is to completely separate my fresh water from grey and or black water period.

OGTerror, great work. Thanks for sharing. However, I tend to agree with Route 66 on the drain rinse - I don't know if it would meet code even with a vacuum breaker, but then I don't know the code either.

I know you're concerned about waste left in the trap, but if you're going to rinse your tanks anyway, wouldn't the last of the water be relatively clean? Even if it isn't, a bucket of fresh water down the drain would take care of it, especially with the cap on the drain.

Yes, exactly what I though of after the fact, as the waste exists the RV's plumbing, fresh water will be pumped through. At the end of flushing and cleaning out the RV's plumbing so should the trap in the dump station should have fresh water at the end.

I would not consider the trap to be overkill.. In fact it may well be required by code depending on where you live.. But for sure it's not overkill.

Sounds like you did a good job

One thing on the double water hookup (I did not look at the photo) IF I were to run a spigot out to the RV's site Id' run a single and use a 2-way manufold setup with valves (Y fitting with valves) in fact.. that is how I"m hooked to the park right now.
